HDMI port stopped working

I have an HP Pavillion dv 2700 laptop with an HDMI output port. In the past I've used it to connect to my hdtv, but it stopped working altogether (video, sound, everything). I know it's not the cable, because I've tested other cables that work with other devices. Anyway, I'm pretty sure the HDMI port is broken. Is there a way I can fix it, or if not is there a way to get it replaced?

8. for CTO notebooks, you need to make sure either you have Intel, NVDIA, or ATI graphics chipset driver.... hdmi audio is usually attached on the graphics chipset family driver

9. restart the nb

10. re-connect the hdmi cable

11. look for the volume icon , right click , click on playback devices, set the HDMI audio as default if it will not do automatic configuration.... NOTE: this is the best practical way to configure sound bec there are cases that when you removed the cable it will still be set to hdmi thus no sound will come fr the defaukt speakers of the nb.

12. for the display you can toggle the display by fn+f4 key but wil intel you wld need to configure it first to work.. to do that right click on the desktop and go to graphic options and set output to Notebook+Digital television, you can also set it to extended display or not by going to disply properties or set it on the graphics control panel.. you have a lot of options actually...
